[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] When the dry powder needs to be dried, first, the operator starts the crusher 7 and the motor 13. The motor 13 drives the transmission wheel and the first bevel gear 15 to rotate. The transmission wheel drives the conveyor belt 11 to rotate through the transmission belt 14. The conveyor belt 11 drives the driving rod 12 to rotate. When the driving rod 12 rotates, the extrusion limit groove 10 drives the sliding plate 9 to slide left and right. The sliding plate 9 drives the L-shaped push plate 8 to slide left and right. When the first bevel gear 15 rotates, it drives the second bevel gear 17 on the left to rotate. The second bevel gear 17 drives the second bevel gear 17 on the right to rotate through the transmission rod 16. The second bevel gear 17 on the right drives the third bevel gear 19 to rotate. The third bevel gear 19 drives the mounting plate 5 to rotate. At this time, the operator puts the dry powder into the feed hopper on the drying box 2. The dry powder falls onto the screen plate 6 under the action of gravity. The screen plate 6 The dry powder is screened, and the unagglomerated dry powder falls into the drying box 2 through the screen plate 6, and the agglomerated dry powder stays on the screen plate 6. When the L-shaped push plate 8 moves to the right, the agglomerated dry powder staying on the screen plate 6 is pushed to move to the right, and the top of the L-shaped push plate 8 blocks the bottom of the feed hopper on the drying box 2, and the agglomerated dry powder falls into the grinder 7 through the right side of the screen plate 6. The grinder 7 grinds the agglomerated dry powder, and the crushed dry powder enters the drying box 2 through the discharge end of the grinder 7. At this time, the heating device in the drying box 2 is started to heat and dry the dry powder in the drying box 2. During drying, the air pump 3 is started, and the air pump 3 discharges the water vapor in the drying box 2 out of the drying box 2 through the suction pipe 4. After drying, the sealing plate at the bottom of the drying box 2 is opened to take out the dried dry powder.
